1 stock represents fractional ownership of the company, which owns physical assets, liabilities, accounts payable, etc. In other words, real life assets.
On the other hand BitCoin fundamentally has no tangible asset backing it. Its price is driven purely by supplly/demand, rather than any sort of book value.
I don't know enough about macro finance to discern whether this is a good/bad/neutral thing for BitCoin, but it's a worthy distinction to make in comparing stock and Btc.
